THE SOCIETE INDUSTRIELLE, OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 311,566, dated February 3, 1885.

Application filed May 2, 1884. (No model.) Patented in Belgium July 15, 1882, No. 58,480; in Germany July 18, 1882, No. 21,127; in Italy April 9, 1884, XVIII, 16,693; XXXIII. I61, and in Austria-Hungary July 10, 1884, No. 13,849, and No. 28,433.

To all whom it may concern.-

Be it known that I, ALBERT CIIOPARD, of Moutier Grandval, Switzerland, have invented a new and useful Improvement in WVatches, of which what follows is a specification.

Letters Patent for this invention have been granted to me as follows: Germany, dated July 18, 1882, No. 21,127; Belgium, dated July 15, 1882, No. 58,480; Austria-I'l ungary, dated July 10,1884., No. 13,849 and No. 28,433, and Italy, dated April 9, 1884, XVIII, No. 16,693; XXXIII, No. 164.

My invention consists of some important modification in the arrangement of the pieces composing a watch. The special purpose of these modifications is to. produce a solid and well-regulated and easily repairable watch at a very low price. I

In the adjoincd drawings, Figure l repre sents a section of the watch-case, showing the manner in which the movement is fixed therein. Fig. 2 represents a top view of the watch mechanism after having taken out the escapement. Fig. 3 shows a back view of the mechanism after having taken off the dial and the cscapement. Fig. Ashows the top, the back, and alongitudinal section of the escapement, WhlOll'lltlS been taken out of the watch mechanism.

The recess 7t is a continuation of the slot that passes from the outer edge of the plate A, and the sides of said slot and recess are parallel with a radial line from the center of the escapementwheel.

In all the figures the same letters refer to the same pieces.

The general disposition of the watch is so made as to render all the parts of it, including the escapement, perfectlyinterchangeable. The three-fourths plate B bears all the wheels but the escapenient and balance wheel. Two or more screws, a, with broad heads, keep the movement in the case. The crown F commands the winding-wheels H and J, with help The clickspringi is shaped 1 of the pinion G.

so as to play like a click, leaning against the periphery of the wheel J, and engaging its end into the teeth of the wheel H. The escapement-wheel is supported by a bridge, M. The escapement, Fig. A, is made in a manner which allows the special workman to finish it entirely, without having in his hands the remainder of the watch. The balance-wheel is supported between the cock L and the bridge K, the latter being introduced into an opening. made for that purpose in the plate A, Figs. 2 and 3. The little bridge k, fixed on the bridge K, bears the ruby. The bridge K and the cock L are connected together by a screw, Z), and of two or three pins, 0. Therefore the workman who makes the escapeincnt may completely finish it without having anything in his hands but the bulancewheel, the spiral spring, and the bridges K. L, and k. The bridge K, entering exactly into the recess K, Fig. 3, countersunk in the thickness of the plate, is fixed therein by means of a screw, (7 which traverses the lengthened hole 0 of the bridge K, Fig. 4, so that the cylinder may be moved to' or from the cscapementwheel. The setting of the hands is made by a push-piece, p, acting upon the usual setting mechanism. The push-piece is supported by a small spiral spring, p, instead of being acted upon, as usually, by a tlat spring fixed on the plate.

Having thus described my invention, what I claim is The bridge K, having an elongated opening therein, the cock L, connected to said bridge by the screw b, and the balance supported by the bearing K L, in combination with the slotted and recessed plate A, and the screw (Z, passing through the opening in the bridge L into the plate A, as set forth.

Signed by me this 17th day of April, A.D. 188i.

ALBERT OIIOPARD.
